Algorithm:-

Step (1):- Start

Step (2):- Declare the variable n, fact, i ;

Step (3):- initialize variable

fact ← 1

Step (4):- Read the value of n

For i ← 1 to n and i is incremented by 1

Step (5):- fact=fact * i

Step (6):- Display fact

Step (7):- Stop

Program:-

#include<stdio.h>

#include<conio.h>

void main()

{

int n, fact=1, i;

clrscr();

printf("Enter the Number");

scanf("%d",&n);

for(i=1; i<=n; i++)

{

fact=fact*i;

}

printf("%d",fact);

getch();

}
